Title: Mercury weigher
Inventor: MURAKAMI YASUHIRO
IPC: H01J9/395
Filed: 1987-12-25
Abstract: PURPOSE:To improve the precision of weighing by holding the recessed part of a rotor. CONSTITUTION:After a long and narrow recessed part 8 is formed in the lengthwise direction on the peripheral surface of a rotor 7 consisting of a metallic round bar, a hole 11 is provided in the central bottom of the recessed part 8 by a drill. By this structure, the hole 11 functions to increase the frictional resistance between the bottom of the recessed part and mercury when mercury in a mercury storage chamber is accumulated in the recessed part 8 in accordance with rotation of the rotor 7. Therefore, mercury which tries to escape the recessed part 8 is surely captured by the surface tension even if a desired quantity of mercury is small.

Title: Linear drive device
Inventor: KLEINERT DIETER
IPC: H02K33/18
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To improve reliability and further reduce switching time by allowing a carriage to support a coil winding that can be loaded by current and at the same time providing a magnetic element at a bearing part for enabling the magnetic element to move in cooperation with the coil winding that is loaded by current. SOLUTION: A linear drive device 9 has a bearing part 2 at nearly a fixed position, thus guiding a carriage 1 in or around the bearing part 2 so that it can be moved. Also, the bearing part 2 has a magnetic element 5. Then, the magnetic element 5 and a coil winding 4 being mounted around the movable carriage 1 cooperate as follows. More specifically, a magnetic field is generated at the coil winding 4 when current is applied. The carriage 1 leaves the bearing part 2 toward right as shown by an arrow 90 owing to the magnetic field. In this manner, the desired movement of the linear drive device 9 is executed.

Title: Air conditioner
Inventor: UKAI SHINJI
IPC: B60H1/00
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To reduce a link operating sound by restricting a vibration of a blowing port changing-over door or a door side link plate in reference to the fact that the link operating sound or irregular sound is generated by a rapid change in speed of a guiding pin tracing a guiding groove under a repelling force of a door packing and its self weight, which causes a vibration of the blowing port changing-over door or the door side link plate. SOLUTION: This device is operated such that a guiding pin 27 formed at a lever side link plate 22 causes a door side link plate 23 and a rib 31 integrally formed with a device case 2 to be contacted to each other until a guide pin 27 formed at a lever side link plate 22 is disengaged from an idle region in the guiding groove 29 formed at the door side link plate 23. With such an arrangement as above, the guide pin 27 is prevented from being disengaged out of the idle region in the guide groove 29 and further the blowing port changing-over door 4 and the door side link plate 23 from being vibrated when an operation of the door side link plate 23 is started so as to reduce operating sound of the link.

Title: Water meter
Inventor: ITOIGAWA NOBORU
IPC: G01F15/06
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the visibility of the amount of water used by preventing the blurring of glass due to dew forming on the lower surface of the glass in winter. SOLUTION: The sum of the thickness of a central recessed part 12a of an organic glass 12A and that of the plastic at the bottom part of a transmitter 22 is made larger than that at the bottom of a register box 7 made of plastic. Even if external temperature decreases in winter, the poor heat conduction of the organic glass 12A and that at the bottom of the transmitter 22 suppresses the temperature reduction on the lower surface of the glass 12A, thus preventing dew from being formed. Side walls 18a and 19a of an upper stand plate 18 and a lower stand plate 19 are engaged to the inner periphery of the side wall of the register box 7, thus suppressing the convection of steam to the lower surface of the organic glass.

Inventor: MARUYAMA SHINICHI
IPC: B60R11/00
Filed: 1993-12-27
Abstract: PURPOSE:To provide the noise restraining structure of a rear parcel part which can improve noise insulating capability without affecting ventilating capability, especially which can decreasing the low-frequency component of noise which invades from a trunk room effectively. CONSTITUTION:Partition walls 13, 14, which partition the primary spaces S1, S3 with the primary opening parts 10a, 10b and the secondary space S4 with the secondary opening part 11b other than an opening part 11a for ventilation, are provided. As a result, the equivalent cross sectional area of a throat part in a Helmhortz resonator, which uses a trunk room as a resonating room and a ventilation passage consisting of the above respective openings as the throat part, is reduced, thus resulting in a decrease in resonance frequency and consequently in a decrease in the sound pressure level of noise which invades a vehicle interior R. Since the openings 10a, 11a for ventilation are not partitioned by the partition walls, ventilating capability is not affected.

IPC: H02G15/013
Filed: 1992-11-17
Abstract: PURPOSE:To prevent a crack from being generated due to a difference of coefficient of thermal expansion between an epoxy resin mold part and an electrode. CONSTITUTION:An electrode, enveloped in an epoxy resin mold part 1, is divided into a plurality of parts in the inside, and each divided electrode 11-1 and 11-2 are electrically connected through a connecting bar 12. Since the connecting bar 12 and the electrodes 11-1, 11-2 are electrically connected by an electric contact 13 slidable in a lengthwise direction of the connecting bar 12, force by thermal expansion/contraction of the electrodes 11-l, 11-2 is absorbed by sliding between this connecting bar 12 and each electrode. Accordingly, the force by thermal expansion/contraction of the electrodes is prevented from being applied to the epoxy resin mold part 1, to relax internal stress thereof, and crack generation or the like can be prevented.
